PORTABLE G 0m or inal application and m n 19,1928, Serial no. 202,000.Divided and um application man 1a,.

This invention relates' to ventilating apparatus, and has reference moreparticularly to ventilating appliances of aportable char-. .acter whichare adapted for a plication to ithe windows of residences and 0t erbuildings to expel foul air from the interior :or inducefresh air fromthe outside, without involving any substantial alterationor defacementof the window structure.

In an ap lication heretofore filed by me on the 19th dhy of March, 1928,Serial 262,608, of which this application-forms a 'vision, I havedisclosed and claimed certain features of the ventilating equipmentherein disclosed, comprising a panel adapted tobe mounted op-- posite awindow and formed with an o ening,

' a :fan motor and fan mounted on sai panel over said opening, and apair of brackets -"adapted to be attached respectively to mem- "20 bersof the window frame with each of the brackets so formed as to engage andhold the panel at both the upper and lower edges of the latter and incombination therewith an extensible telescoping closure strip hinged atit's forward edge to the lower edge of the panel and at its rear freeedge adapted to rest on the'top of the, upper sash when the latter is in-lowered position; the inner telescoping member of said closure stripbein provided on its free edgewith a spacer ri mg on the outer face ofthe up r sash as the latteris raised and lowered in order to prevent thefree edge of the closure strip from striking the to cross bar of thesash as the'latter is being owered.

According to my present invention, I provide on each side of the uppersash a pair of de nding push and pull rods, for raising an lowering theupper sash without havin to first remove the panel and these push andpull rods also serve the additional function of guides and spacers forthe free edge of the closure strip preventing any interference of thelatter with the tcp stile of the upper sash as the latter is beinglowered. 1

In the accompanym drawings illustrating the practical and "pre erredembodiment of the resent invention- Fig. 1 is a front elevation of aWlIldOW frame showing the upper sash lowered and my. improvedventilating outfit applied thereto. v

, Fi' 2 is a vertical transverse section showin t e upper sash in raisedposition.

I g. 3 1s a vertical transverse section showing the upper sash inlowered position and the free edge of the closure strip resting on .theupper cross bar thereof.

Fig. 4 is .a vertical section, broken out, in the plane of one of thepanel supporting stri s. ig. 5 is an enlarged perspective detail of theextensible'closure strip, showing the under side thereof.

Fig. 6 is a perspective detail of one of a pair 'of push and pull rodswhich serve for raising and lowering the upper sash and also astrackways for the free edge of the closure strip.

Fig. 7 is a perspective detail of a bracket detachably engaged by thepush and pull rods shown in Fig. 6.

Referring to the drawings 10 designates the'top bar and 11 the side barsof a conventional window frame, and 12' and 13 designate 75 tively theupper and lower window sashes. 14 designates a rectangular panelconveniently made of wood and formed with a central hole 14 in which ismounted an annular frame member 15 formed with radial arms 16 and a ring17 in which is supported an electric'motor 18 operating a direct drivenventilating fan 19 which serves-to move air through the ring frame 15when theupper sash 12 is lowered aslshown in Fig. 3.

The panel 14 is supported in working position by means of a pair ofmetal strips 20 formed on their lower ends with upturned hooks 21 thatsupport the lower edge of the panel, as clearly shown'in Fi 4, and ontheir upper ends with downturn hooks 22 which overlap the upper edge ofthe panel. The downturned llmb of the hook 22 is formed with an upwardlyturned or re-entrant terminal portion 22' that bears against the outer"face of the panel 14, and the downturned portion of the hook has a tapopening to 7 receive a thumb screw 23 whic bears against the upturnedorre-entrant portion 22. and forces the latter tightly against the panel.

By this means the upper portion of the panel is heldtightly against thewindow frame, and by retracting the thumb screw 23 the panel may bereadily entered endwise into, and withdrawn from, its supportingbrackets in an obvious manner.

When the up er sash is lowered, as shown in Fig. 3, in or er to enablethe fan to functionefliciently it is desirable to close the open ingbetween the lower edge of the panel and the top of the lowered sash. Thepanel 14; in practice is made wide enough to serve the widest window ofany dwelling or room in which it may be used, and when applied to anarrower window, can overhang the sideframe members of the latter, ifnecessary,

without interfering with its proper func-' tioning. The closure strip,however, must be adjustable lengthwise to fit the width of theparticular sash with which it cooperates, and for this purpose theclosure strip consists preferably, as best shown in Fig. 5, of a sheetand the member or members 28 and the main member 24: are so adjustedthat their combined length will equal the width between the sash groovesof the upper sash 12.

When employing a ventilating panel of this character which, when inplace, covers the major portion of the upper window sash, it isdesirable to provide means for conveniently raising and lowering theupper sash without having to first remove the panel. As a convenientmeans for this purpose I preferably employ on each side of the uppersash a pairof push and pull rods 30. The upper end of each rod is bentto form-a hook 31 adapted to detachably engage with a horizontalU-shaped bracket 32 mounted on the upper end of each sash stile, asshown in Figs. 1, 2 and 3. The vertical limb of the bracket and itsupper horizontal limb are provided with holes 33 and 34 respectively(Fig. 6) through which the hook 31 may be successivelyentered, asclearly shown in Fig. 2. The rod 30,111 the closed position of the uppersash, depends somewhat below the lower edge of the panel, as shown inFig. 2, and may be formed on its lower end with a ring 35 convenientiyengaged by the linger. By reference to ig. 2 it will be observed thatthe free edges of the extensions 28 oil the closure strip ride on therods 3i), thus spacing the free edge of the closure strip the stiles ofthe up per sash, preventing any scratching or marring of the surfacefinish of the latter and also serving to prevent collision of the freeedge of the closure strip with the top bar of the upper sash whenlowering the latter. During the lowering of the upper sash the free edgeof the closure strip rides on thepush and pull rods 30 as shown in Fig.2, and, as the upper sash reaches its fully lowered position shown inFig. 3, the free edge of the closure strip rides off the upper ends ofthe rods 30 and comes to rest on the top cross bar of the lowered sash,in the manner clearly shown in Fig. 3.

In the case of the extensible closure strip herein shown, wherein theextension members 28 are mounted in the guide flanges 25 and 26, thepull rods prevent flange 26 (which is somewhat narrower than the uppersash) from striking against the lower edge of the top stile of the uppersash during the lowering of the latter. However, where a single orunitary closure strip may be employed, the push and pull rods 30maintain the free edge of the closure strip out of contact with thestiles of the upper sash, preventing, as above stated, the scratching ormarring of the surface finish of the latter.
